The invention relates to a method for manufacturing a multilayer strucute on a first substrate, the method including: using the first substrate made of a first material having a Young's modulus Ev and a thickness ev, and using a second substrate covered by the multilayer structure, the second substrate being made of a second material having a Young's modulus Es that is different from the Young's modulus Ev and a thickness es, the thicknesses es and ev complying, plus or minus 10%, with the relation (I); molecularly bonding the first substrate and the multilayer structure together; and removing the second substrate.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A method of manufacturing a multilayer structure on a first support, the method comprising the successive steps of: providing the first support made of a first material having a Young's modulus Ev and a thickness ev, and a second support covered with the multilayer structure, the second support being made of a second material having a Young's modulus Es different from Young's modulus Ev, and a thickness es, thicknesses es and ev verifying, to within 10%, relation: e s = E v E s e v ; performing a molecular bonding between the first support and the multilayer structure; and removing the second support.
2. The manufacturing method of claim 1 , wherein the second support initially has a thickness greater than thickness es, the method further comprising, before the bonding step, thinning the second support down to thickness es.
3. The manufacturing method of claim 1 , wherein thicknesses es and ev are greater than 50 μm.
4. The manufacturing method of claim 1 , wherein the second material is single-crystal silicon.
5. The manufacturing method of claim 1 , wherein the first material is isolating.
6. The manufacturing method of claim 1 , wherein the first material is transparent.
7. The manufacturing method of claim 1 , wherein the first material is glass.
8. A support for a multilayer structure intended to be bonded to an additional support made of a first material having a Young's modulus Ev and a thickness ev, the support being made of a second material having a Young's modulus Es, different from Young's modulus Ev, and a thickness es verifying, to within 10%, relation: e s = E v E s e v .
9. The support of claim 8 , wherein the second material is single-crystal silicon.
10. The manufacturing method of claim 2 , wherein thicknesses es and ev are greater than 50 μm.
11. The manufacturing method of claim 2 , wherein the second material is single-crystal silicon.
12. The manufacturing method of claim 3 , wherein the second material is single-crystal silicon.
13. The manufacturing method of claim 2 , wherein the first material is isolating.
14. The manufacturing method of claim 3 , wherein the first material is isolating.
15. The manufacturing method of claim 4 , wherein the first material is isolating.
16. The manufacturing method of claim 2 , wherein the first material is transparent.
17. The manufacturing method of claim 3 , wherein the first material is transparent.
18. The manufacturing method of claim 4 , wherein the first material is transparent.
19. The manufacturing method of claim 5 , wherein the first material is transparent.
20. The manufacturing method of claim 19 , wherein the first material is glass.
